ID 1.16.3.2 DE bacterial non-heme ferritin. CA 4 Fe(2+) + 6 H2O + O2 = 12 H(+) + 4 iron(III) oxide-hydroxide. CC -!- Ferritins are intracellular iron-storage and detoxification proteins CC found in all kingdoms of life. CC -!- They are formed from two subunits that coassemble in various ratios CC to form a spherical protein shell. CC -!- Thousands of mineralized iron atoms are stored within the core of the CC structure. CC -!- The product of dioxygen reduction by the bacterial non-heme ferritin CC is hydrogen peroxide, which is consumed in a subsequent reaction.
